Onkyo's TX-NR818 home theater receiver is an audio and video workhorse. Its THX® Select2 Plus™ badge of certification means it can reproduce riveting, accurate movie sound that'll have you glued to your TV screen. You also get the latest surround sound options, including Dolby® TrueHD and DTS-HD™ Master Audio, two high-resolution formats found on many Blu-ray movies. The 'NR818 uses Onkyo's WRAT (Wide Range Amplifier Technology) and a high-current power supply to deliver dynamic, punchy sound that stays clean even at higher volume levels.

Amazing video quality is at the dual core

The 'NR818 boasts two fantastic video processors that work together to deliver superlative images. The HQV® Vida™ circuit upscales analog content to 1080p. And the Marvell Qdeo™ chip adds a crisp finish to the signal. Eight HDMI inputs — including one in front for easy access — let you connect all your high-def equipment. Plus there's ISF (Imaging Science Foundation) video calibration to dramatically improve picture quality. Each video input source is independently calibrated to achieve the best possible performance from your connected HDTV. And let's not forget that there are two HDMI outputs to connect to your TV and projector. But movies, video games and TV are just the beginning.

Ready to entertain you

Just plug your iPod® into the front-panel USB port to get the beat started. This connection delivers a digital signal directly to the 'NR818's superior processor so your music sounds awesome. Use the Ethernet port or the optional Onkyo Onkyo UWF-1 Wi-Fi adapter to connect the 'NR818 to your broadband home network and you'll get easy access to the music files stored on your networked computers. Then dive into thousands of Internet radio stations — so you can enjoy entertainment from every corner of the planet. Your potential playlist just expanded exponentially. Want more? You also gain the ability to stream music from Internet services like Pandora® Internet radio, Spotify®, Sirius/XM® Internet radio, Rhapsody® and more (may require registration and subscription fees).

What would you like to do with seven channels?

Most home theater setups are 5.1-channel, but the 7.2-channel TX-NR818 offers ways to experience even greater wraparound realism. You can drive a pair of back surround speakers placed in the rear of your room to create greater spatial accuracy: get ready to duck when a mortar round screams overhead and explodes behind you. Or use those channels for "height" speakers, so when the incoming rounds start to fall, you may want to take cover. If your front speakers have dual sets of connectors, you can re-assign these two channels and "bi-amp" the speakers — doubling the power they receive is a great way to get every last ounce of performance from them. Or there's always the convenience of using those surround channels to play music on the deck speakers while the kids continue uninterrupted gaming in the theater room.

User-friendly features

The 'NR818 comes equipped with Audyssey® sound-shaping tools to automatically balance and equalize the sound based on your room's acoustics. Audyssey Dynamic Volume maintains optimum dynamics, so gone are the commercial sponsor's surprise sonic attacks. Onkyo's InstaPrevue™ system lets you see thumbnails of digital video sources on-screen, taking out the guesswork of which HDMI source is plugged into what port. You also get a graphic user interface to make control easy and intuitive with overlays on your TV screen. And you can download a free app to use your iPhone® and Android™ devices as powerful Wi-Fi® system remotes.

Receivers: Your ticket to sensational sound

Your receiver powers your speakers and lets you connect and select your entertainment sources. But a great receiver does a lot more  it ignites your emotions. From the passion of a favorite musical artist, to the crossfire of a super-charged movie soundtrack, to the intensity and immersion of a fast-paced video game, your receiver is the key to experiencing and enjoying it in full.

Product Research

Audio Features

7.2ch AV Receiver: The Onkyo TX-NR818 features a 7-channel
amplifier rated at 135 watts (into 8-ohms, at 20Hz-20kHz, with 0.08%, driving 2
channels) and two mono subwoofer preamp outputs. The 7-channel amplifier can be
configured in four ways.

7.2ch Surround: The Onkyo TX-NR818 provides 7.2ch surround in
your main listening area. You can listen to either surround back, front
high, or front wide speakers.

Front Bi-Amp: The Front High/Zone 3
speaker terminals can be reassigned and used along with the Front terminals
to bi-amp the front speakers, providing improved bass & treble performance.
When bi-amping the front speakers, the receiver is limited to a 5.2ch speaker
system in the main room and you cannot power additional speakers in Zone 2
or 3.

Powered Zone 2: The Front Wide/Zone 2 speaker terminals
can be reassigned to power a pair of speakers in Zone 2. This
configuration restricts the main listening room to 5.2ch surround (no
surround back or Front High/Wide speakers).

Powered Zone 3: The Front High/Zone 3 speaker terminals
can also be reassigned to power a pair of speakers in Zone 3. This
configuration restricts the main listening room to 3.2ch surround (no
surround/surround back or Front High/Wide speakers).

WRAT (Wide Range Amplifier Technology): WRAT is based around
a low negative-feedback circuit topology that works to reduce signal noise and
distortion across the frequency range. A "closed ground-loop circuit" design is
employed, in which each circuit has a separate link to the power supply. This
helps to cancel individual circuit noise and keep the ground potential free of
distortion. High Instantaneous Current Capability (HICC) enables WRAT amplifiers
to immediately cancel the speakers' reflex energy and instantaneously send out
the next signal. The same high current better manages speaker impedance
fluctuations, which can negatively affect performance.

H.C.P.S. (High Current Power Supply): Under the
anti-resonant cover of any Onkyo receiver, you'll instantly notice the High
Current Power Supply (H.C.P.S.) transformer. With its huge, isolated power
supply design and high-capacity filter capacitors, it delivers the large amounts
of power necessary for reproducing the wide dynamics of movie soundtracks and
the detail and clarity of your music.

Optimum Gain Volume Circuitry: Optimum Gain Volume Control adjusts the
gain so that less than half the amount of attenuation is needed, ensuring the
signal never comes close to the noise floor. This protects the signal against
noise, resulting in a dramatically clearer sound.

Note: Dolby Digital and DTS listening modes can only be
selected if your audio source is connected to the AV receiver via a digital
audio connection (HDMI, optical, or coaxial). To enjoy true 7.1ch Dolby
Digital TrueHD and DTS-HD surround sound, the receiver must be connected to
your Blu-ray player via HDMI.

THX Certified: The TX-NR818 AV receiver is
THX certified. Founded by George Lucas, THX develops stringent standards
that ensure movies are reproduced in movie theaters and home theaters just as
the director intended. From early design concepts to product rollout, THX works
with its manufacturing partners at each step of product development. Every
detail is meticulously mapped to the THX performance standards. And THX
engineers spend countless hours testing and analyzing each product for sound
quality, usability and interoperability. The result of this collaborative
process is a THX Certified receiver, amplifier or pre-amplifier designed from
the ground-up to present your favorite movies, music, and games in 5.1ch to
7.1ch surround sound loud and clear at studio reference volumes.

THX: THX Modes (Cinema, Music, or Game) carefully
optimize the tonal and spatial characteristics of the soundtrack for
reproduction in the home-theater environment. They can be used with various
multichannel sources. Surround back speaker output depends on the source
material and the selected listening mode.

THX Ultra2+ (w/ THX Loudness Plus): The ultimate
benchmark for home audio performance, THX Ultra2 Plus is specified for rooms
where the screen-to-seat viewing distance is more than 12 feet and the room
volume is 3,000 cubic feet or greater. This mode expands 5.1-channel sources
for 7.1- channel playback. It does this by analyzing the composition of the
surround source, optimizing the ambient and directional sounds to produce
the surround back channel output. You can choose between Cinema, Music, or
Game mode. THX Loudness Plus is a volume control technology featured in THX
Ultra2+ certified components. With THX Loudness Plus, home theater audiences
can experience the rich details in a surround mix at any volume level. THX
Loudness Plus compensates for the tonal and spatial shifts that occur when
the volume is reduced by intelligently adjusting ambient surround channel
levels and frequency response. The THX Loudness Plus feature can be applied
when listening in any THX listening mode.

Onkyo Original DSP Modes: Onkyo's Original DSP Modes,
combined with Dolby Digital/DTS/Dolby Pro Logic processing, produce more
realistic, powerful sound effects for your movie and music sound tracks based on
the type of content and your home theater setup. You can choose from the
following:

All Ch Stereo: Stereo sound from all speakers. Ideal
for background music.

Full Mono: All speakers output the same sound in mono.

Theater-Dimensional (T-D): Theater-Dimensional
circuitry takes the complexity out of conventional surround-sound setups and
lets you experience the excitement of surround sound from as few as two
ordinary speakers. Theater-Dimensional's unique multi-speaker modes let you
place up to five speakers conveniently by the TV, for the most realistic
virtual-surround sound possible.

Audyssey MultEQ XT32 Automatic Speaker Setup: With the
supplied speaker setup microphone, Audyssey MultEQ XT32 determines the
number of speakers connected, their optimum crossover frequencies, and their
distances from the primary listening position, then adjusts each
automatically. The room's acoustical properties are then measured and
corrected over the listening area in both the frequency and time domain.
There is a threaded insert on the bottom of the microphone so it can be
mounted on a tripod for accurate listening position placement. Up to 8
listening position measurements are taken to optimize the surround effect
for a broad area. If you prefer you can also setup your speaker system
manually.

Audyssey Dynamic EQ: Audyssey Dynamic EQ solves the
problem of deteriorating sound quality as volume is decreased by taking into
account human perception and room acoustics. Dynamic EQ selects the best
possible frequency response and surround levels moment-by-moment as volume
is changed. The result is bass response, tonal balance and surround
impression that remain constant despite changes in volume. Audyssey Dynamic
EQ combines information from incoming source levels with actual output sound
levels in the room, a prerequisite for delivering a loudness correction
solution. Audyssey Dynamic EQ works in tandem with Audyssey 2EQ to provide
well-balanced sound for every listener at any volume level.

Audyssey Dynamic Volume: Audyssey Dynamic Volume solves
the problem of large variations in volume level between television programs,
commercials, and between the soft and loud passages of movies. Dynamic
Volume looks at the preferred volume setting by t he user and then monitors
how the volume of program material is being perceived by listeners in real
time to decide whether an adjustment is needed. Whenever necessary, Dynamic
Volume makes the necessary rapid or gradual adjustments to maintain the
desired playback volume level while optimizing the dynamic range. Audyssey
Dynamic EQ is integrated in Dynamic Volume so that as the playback volume is
adjusted automatically, the perceived bass response, tonal balance, surround
impression, and dialog clarity remain the same whether watching movies,
flipping between television channels, or changing from stereo to surround
sound content.

Dolby Pro Logic II Music Settings: While listening in
the Dolby Pro Logic II Music format, there are three further enhancements
you can adjust; Panorama: (broadens the front stereo image to the surround
speakers to provide a wraparound effect), Dimension (allows you to move the
sound field forward or backward), and Center Width (allows you to adjust the
width of the center channel).

Pro Logic IIz Height Gain: The Height Gain Control in
Dolby Pro Logic IIz enables the listener to select how much gain is applied
to the front high speakers. There are three settings, "Low", "Mid" and
"High", and the front high speakers are accentuated in that order. While
"Mid" is the default listening setting, the listener may adjust the Height
Gain Control to their personal preference.

Center Image: In the Neo:6 Music mode, the Center Image
feature adjusts the output of the left and right channels relative to the
center channel, allowing you to make the center channel more or less
dominant as needed. This improves the image of the center channel,
especially when the listener is off-center. Adjustment varies from 5
(nothing subtracted from the L/R channels) to 0 (L/R channel output is cut
in half).

Screen Centered Dialogue: By using the front high
speakers, this function moves the center image of the dialogue upwards, so
that the image of dialogue is fixed to the display height.

Listening Angle: While listening in the Theater
Dimensional mode you can adjust the listening angle to either Wide (if
listening angle is 40°) or Narrow (if listening angle is 20°).

THX Loudness Plus: THX Loudness Plus is a volume
control technology featured in THX Ultra2 Plus certified receivers. With THX
Loudness Plus, home theater audiences can experience the rich details in a
surround mix at any volume level. THX Loudness Plus compensates for the
tonal and spatial shifts that occur when the volume is reduced by
intelligently adjusting ambient surround channel levels and frequency
response. The THX Loudness Plus feature can be applied when listening in any
THX listening mode.

Dolby Volume: Dolby Volume automatically adjusts the difference in
volume levels which can occur between different contents or source components,
freeing the user from having to make volume adjustments. Also, by adjusting the
frequency balance according to the playback volume, it recreates the original
source audio. Dolby Volume therefore provides comfortable listening, effectively
controlling the volume level difference without unnatural changes in volume or
sound quality to recreate the balance and nuance of the source audio.

Dialog Normalization: Dialog Normalization (DialogNorm) is a feature
of Dolby Digital, which is used to keep the programs at the same average
listening level so the user does not have to change the volume control between
Dolby Digital, Dolby Digital Plus, and Dolby TrueHD programs.

CinemaFilter: Using the CinemaFilter you soften overly bright movie
soundtracks. Movie soundtracks are typically mixed for a large theater (relative to your
home theater) with lots of soft seats and thick curtains on the walls. Home theater
settings often lack these high frequency absorbing wall treatments, making the soundtrack
sound too bright. CinemaFilter accounts for this and for many movies sounds more natural
at home.

Music Optimizer: While MP3 or AAC files may sound fine
through the headphones of your portable digital player, the limitations of these
files can be exposed when played back through a quality home entertainment
system. This is because a significant amount of high-frequency bit information
is lost during the file-compression process. To counter this, Onkyo has designed
the Advanced Music Optimizer to compensate for lost bit information and improve
the quality of compressed audio signals. This results in a clearer and more
expansive sound. Also included in this technology is a loudness correction
feature that further improves the audio character of compressed files. The Music
Optimizer function only works with PCM digital audio input signals with a
sampling rate below 48kHz and analog input signals.

Re-EQ: With the Re-EQ function, you can compensate for harsh
high-frequency content, making it more suitable for listening.

Late Night Feature: The Late Night feature limits the dynamic
range of Dolby Digital recordings. Limiting the dynamic range makes it easier to
find a volume that ensures the quiet sounds are not too quiet and the loud sounds
are not too loud for night time listening. This allows you to comfortably listen
to without the need to constantly adjust the volume to keep from waking family/neighbors.
The choices are: Off, Low, and High. This feature only works
with Dolby Digital Encoded software and the depth
of the feature will vary based on the individual
software package.

Bass & Treble: You can independently adjust the Bass (50Hz)
and Treble (20kHz) of the TX-NR818 from -10 to +10 dB.

IntelliVolume: With IntelliVolume, you can set the
input level for each input (+/-12dB) selector individually. This is useful
if one of your source components is louder or quieter than the others. This
function does not work in Zone 2.

Maximum Volume: Use this feature to set the receiver's
maximum volume level. This feature is useful to avoid turning the volume too
loud by mistake. You can set the Max Volume from 30-79 (max), or Off (disabled).

Power On Volume: Use this feature to set the volume
level when the power is turned on. You can choose between Last (same as the
volume when the unit was turned off), Min (0), or 1-78.

Headphone Level: With this setting, you can specify the
headphone volume (+/-12dB) relative to the main volume. This is useful if
there's a volume difference between your speakers and your headphones.

Assignable Digital Inputs: The Onkyo receiver is equipped
with three optical digital inputs (2 rear/1 front) and three coaxial digital inputs. All four digital inputs
are assignable. You can choose auto decoding , PCM, or DTS for the digital audio
inputs. Auto will decode the signal in its original form (Dolby Digital, DTS,
PCM, etc), PCM decodes the signal to 2-channel, while DTS decodes only DTS
formatted sources.

Phono Input: The Onkyo A/V receiver is fitted with a Phono input and ground
terminal for connection of a turntable (MM).

Headphones: When headphones are plugged into the full-size
1/4" jack on the front panel, all the speakers are automatically muted.
When you connect an iPod or iPhone to the USB port on this receiver, no sound
will be output from the headphone jack.

Video Features

HQV Vida Video Processor (VHD1900): The TX-NR818 is equipped
with the sophisticated HQV Vida VHD1900 processor to enhance the quality of both
standard-definition and high-definition video sources. The chip employs
multi-cadence tracking, expanded 12-bit color processing, and four-field
motion-adaptive de-interlacing to optimize video quality and detail. Two new HQV
technologies are incorporated into the VHD1900: "Auto HQV" works to
automatically enhance the incoming image, while "HQV StreamClean" cleans up
compressed video in real time by eliminating mosquito and block noise from
lower-quality sources such as online video sites.

Marvel Qdeo Video Chip for 4K Upscaling: The Onkyo TX-NR818
utilizes a Marvel Qdeo Video Chip for 4K Upscaling and video processing. The
Marvel Qdeo Video Chip produces quiet and natural video, free from noise and
artifacts. Analog video signals (composite/component) are converted to HDMI and
can be scaled to the resolution set in the menu: Through (no scaling), Auto
(automatically scaled to the highest resolution supported by the display), 480p,
720p, 1080i, 1080p, or 4K.

HDMI (v1.4): The TX-NR818 has eight HDMI v1.4 inputs (7
rear/1 front). The front jack is fixed as the Aux input, while the six rear
panel jacks are assignable to any of the other inputs. There are two HDMI
monitor outputs; both outputs can be active simultaneously and will pass digital
audio and video. The HDMI inputs will support uncompressed standard or high
definition digital video along with the following audio signals: 2-channel
linear PCM, Multichannel linear PCM, and Bitstream. The receiver's HDMI
circuitry allows the receiver to output an HDMI audio signal from its speaker
outputs, headphone out, and HDMI out so you don't have to run additional analog
or digital cables. The HDMI inputs accept 480i, 480p, 720p, 1080i, and 1080p
video
signals. The analog video inputs (composite/component) are converted to HDMI
for transfer to the TV.

Note: The 2 HDMI outputs display the same video signal
and can be used simultaneously.

Front-Panel HDMI (MHL) Port: The front-panel HDMI port is designed for
the connection of select mobile phones and other portable electronic devices using the
new MHL standard. Simply plug your MHL compatible smartphone into the receiver's
front-panel HDMI port using the HDMI cable that is included with your mobile
phone. MHL allows you to display full 1080p video and still images on
your HDTV with up to 7.1 channels of surround sound. By programming the A/V
receiver's supplied
remote control with the appropriate numeric code, you can use it to operate your
connected
MHL-enabled smartphone. Your connected smartphone is also recharged upon
connection, and no separate power supply for the device is necessary while
connected to the receiver. The A/V receiver is compatible with Android
smartphones from Samsung, HTC, and LG (must support MHL standard); as of
6/7/2012.

x.v.Color: The AV receiver supports x.v.Color, offering a
wider color range than the current broadcast standard. For the x.v.Color feature
to be useful, the entire video production chain must be compatible
(camera-editing-format-player-display).

Deep Color: The Onkyo receiver also supports Deep Color
which allows the color depth of video signals passing through HDMI to be raised.
The number of colors that could be expressed by 1 pixel was 24 bits (16,777,216
colors) with a standard HDMI jack. However, the number of colors which can be
expressed by 1 pixel is 36 bits with a Deep Color enabled HDMI jack. Since the
gradation of the depth of a color can be expressed more finely with more bits,
continuous color changes can be more smoothly expressed. For the Deep Color
feature to be useful, the entire video production chain must be compatible
(camera-editing-format-player-display).

HDMI Through: When enabling the HDMI Through function,
regardless of whether the AV receiver is "on" or in "standby" both audio and
video streams from an HDMI input will be output to your television, via the
receiver HDMI monitor output. You can select between 3 HDMI Through functions
modes.

Last: The HDMI Through function is activated on the
input source selected at the time of setting the AV receiver to the
"standby" mode.

ARC (Audio Return Channel): This feature allows audio to be
sent from your compatible HDTV to your receiver through the same HDMI cable
already being used to send audio and video to your HDTV. This eliminates the
need for extra cables connected to your television. The receiver's main HDMI
monitor output supports the ARC function, while the sub HDMI monitor output does
not.

InstaPrevue: InstaPrevue technology provides a live video
thumbnail of the available content on your devices connected to the receiver via
HDMI. As a result, you can preview audio/video
streams coming from up to 5 HDMI inputs previously assigned to input selectors
on your HDMI connected TV. Even with multiple components connected
to receiver through HDMI, you can
easily switch between inputs as their previews are displayed on a single screen
on your television.
You can even use the InstaPrevue feature for Picture-in-Picture. You can specify
the number of preview thumbnails, as well as their positioning
on-screen.

Note: If no video
signal are present, the thumbnails will be filled in black. With 3D video
signals, the image may not be properly rendered on the preview thumbnails of
InstaPrevue.

Auto Lip Sync: The Lip Sync function can automatically
synchronize HDMI audio and video that has gotten out of sync due to the
complex digital video processing being performed by your HDMI-compatible TV.
With HDMI Lip Sync, the audio delay required to synchronize the audio and
video is calculated and applied automatically by the AV receiver.

A/V Sync Control: Occasionally, you may need to manually
adjust the audio/video signals that are not
properly synchronized manually. Typically when using a progressive scanning DVD player. You
can correct this by delaying the audio; options are 0 (no delay) to 800 milliseconds,
in 10 millisecond steps.

Game Mode: If video signal delay occurs during
playback on a video component (i.e., game console), select the
corresponding input source and set the "Game Mode"
setting to "On". The
delay will decrease but in return the picture quality will become poor.

Film Mode: Video (Film Mode detection is not
applied and the input signal is handled as a video source) Auto (detects
whether the input signal is a video or a movie. If it is a movie, the
appropriate conversion is applied).

Edge Enhancement: With Edge Enhancement, you can
make the picture appear sharper.

Noise Reduction: With this setting, you can reduce
noise appearing on the screen.

Mosquito NR: With Mosquito Noise Reduction, you can
remove the shimmering or haziness that sometimes appears around objects
in the picture. Mosquito noise can be an issue with overly compressed
MPEG content.

Block NR: With Block Noise Reduction, you can
remove the block distortion that sometimes appears in the picture. Block
noise can be an issue with overly compressed MPEG content.

ISF (Imaging Science Foundation) Video Calibration: The
Onkyo TN-NR818 offers ISF (Imaging Science Foundation) video calibration for
optimal video performance. The receiver has been designed to incorporate setup
and calibration standards established by the Imaging Science Foundation (ISF).
The ISF has developed carefully crafted, industry-recognized standards for
optimal video performance and has implemented a training program for technicians
and installers to use these standards to obtain optimal picture quality from the
receiver. Accordingly, Onkyo recommends that setup and calibration be performed
by an ISF Certified installation technician.

Note: Apple iPod/iPhone software updates may change
functionality results. If you download a newer software version, you may
need to reset the unit and your iPod/iPhone to regain functionality. If this
doesn't work, you may need to wait until a newer software update is
available.

Convenience Features

On-Screen GUI (via HDMI): The Onkyo AV receiver offers an
on-screen setup menu (GUI) through its HDMI output. The on-screen display offers
multiple language text, such as - English, French, Spanish, German, and Italian.
If your TV is connected to the composite video or component video monitor
output, you will need to use the AV receiver's front-panel display when changing
settings.

Hidden Front-Panel Controls: The majority of the receiver's
front-panel control are hidden behind a manual fold-down panel. This gives the
AV receiver a very clean, sleek look.

Multi-Zone: The TX-NR818 offers three Zones; a multi-channel
audio/video system in your main listening room (Main Zone), a stereo audio only
system in a second room (Zone 2), and another stereo audio only system in a
third room (Zone 3).

Zone 2: Zone 2 allows playback of a separate analog source
in 2-channel stereo in an additional room of your home. Zone 2 features
line-level outputs and speaker outputs. This way, Zone 2 can be powered by a
separate integrated amplifier (keeping 7.2ch playback in your main room) or by the
TX-NR818's built-in amplifier (limiting the main room to 5.2ch).
When powering Zone 2 with the receiver's built-in amplifier, listening modes
that require surround back or front high/wide speakers are unavailable. You
cannot power Zone 2 with the receiver's built-in amplifier, if you are bi-amping
your front speakers. The volume of Zone 2 is controlled from the receiver when
using the speaker outputs and from your add-on integrated amp when using the
line-level outputs.

Zone 3: Zone 3 allows playback of a separate analog source
in 2-channel stereo in a third room of your home. Zone 3 features
line-level outputs and speaker outputs. This way, Zone 3 can be powered by a
separate amplifier (keeping 7.2ch playback in your main room) or by the
TX-NR818's built-in amplifier (limiting the main room to 3.2ch).
When powering Zone 3 with the receiver's built-in amplifier, listening modes
that require surround/surround back or front high/wide speakers are unavailable. You
cannot power Zone 3 with the receiver's built-in amplifier, if you are bi-amping
your front speakers. The volume of Zone 3 is controlled from the receiver when
using the speaker outputs and from your add-on integrated amp when using the
line-level outputs.

Note: *Compatible Sources -Only Tuner, analog, USB, and
Network audio sources can be sent to Zone 2 or Zone 3. You must currently be
listening to a USB device or Network audio source in the Main Zone to initially
select USB or Network as a source in Zone 2 or Zone 3 (then you can switch the
Main Zone to any source you desire). *Incompatible Sources -You cannot select different AM/FM radio stations
or listen to USB and Network content in separate Zones at the same time.
Optical/coaxial digital and HDMI audio sources are not output to Zone 2 or
3. You cannot output any video signal to Zone 2 or 3.

Whole House Mode: The Whole House Mode is useful when you want to
simply add extra background music to your home party. This mode allows you to
enjoy the same stereo music as the main room in separate rooms (Zone 2/3). The
Whole House Mode selects the same input source for Zone 2/3 as the main room.
During the Whole House Mode, stereo playback is automatically selected for all
zones. The Main Zone & Zone 2/3 will play at the same volume level.

Name Edit: You can enter a custom name for each individual
input selector and radio preset for easy identification. When entered, the
custom name will appear on the display. This function cannot be used for the
Network and USB input selectors.

Display Dimmer + Screen Saver: The display brightness has three settings;
Dim, Dimmer, and Normal. If there is no video signal on the current input source
and no operation for a specific time, a screen saver automatically comes on. You can set the time
(3min/5min/10min/off) until the screen saver activates itself. Once active, the
screen saver will go off and the screen will return to its previous state if the
AV receiver is operated in any way.

Auto & Hybrid Standby: The AV receiver will automatically go into Standby mode,
if there is no operation for 30 minutes with no audio/video signal input. The Onkyo TX-NR818 features "Hybrid Standby" mode to save
energy and provide greater levels of convenience. Hybrid Standby Mode provides
"HDMI through" functionality and maintains a local network connection while the
receiver is essentially powered down. This allows the user to watch TV without
turning the whole surround system on. Furthermore, when on Hybrid Standby, the
home theater may be powered up from "cold" using the Remote Apps for iPod
touch/iPhone and Android.

Sleep Timer: From the remote, you can set the unit to automatically
turn off after as much as 90 minutes or as little as 10 minutes; choices are presented in
10 minute increments.

Optional Bluetooth Adapter (sold separately): The Onkyo
UBT-1 Bluetooth USB Adapter (580UBT1, sold separately) lets you wirelessly
stream music from your Bluetooth-enabled smartphone, portable audio player,
tablet, laptop, or PC to the Onkyo A/V receiver. The Onkyo UBT-1 is fitted with
a male USB (type-A) connector which plugs into the Onkyo receiver's USB (type-A)
port. The Onkyo UBT-1 is Bluetooth version 3.0 certified and lets you wirelessly
stream music from many Bluetooth-enabled devices supporting A2DP (Advanced Audio
Distribution Profile). The Onkyo UBT-1 is equipped with apt-X, an audio coding
technology that works within Bluetooth to wirelessly deliver CD-quality audio
from your Bluetooth-enabled device to the Onkyo A/V receiver.

Note: Due to the differences in Bluetooth technology, some
Bluetooth enabled devices may be incompatible, function improperly, or may
not support all features when used with the Onkyo UBT-1.

Onkyo components via simple commands from a single-button press, using the
included IR remote control. There are three Activities buttons (My Movie/My
TV/My Music) that can be programmed to perform a sequence of commands with just
one button press; each macro button can perform up to 32 commands.

RI Remote Control Jack: The 1/8" RI remote control jack
allows you to connect this receiver to other compatible Onkyo components.

IR Input/Output: The 3.5mm IR input jack allows you to
control the receiver without line-of-sight access using an optional IR
remote control system and locating the remote sensor in sight. The 3.5mm IR
output jack allows you to send the control signals to an additional
components.

12 Volt Trigger: The two 3.5mm minijack outputs can be
connected to the 12-volt trigger input on a power amplifier in Zone 2 or
Zone 3. When the zone is turned on, a 12-volt trigger signal is output.

RS-232C Port: The TX-NR818 has an RS-232C port for
connection to external control systems from companies such as AMX or
Crestron.

Remote Apps for Apple iOS Devices and Android Smartphones: The Onkyo
Remote App 2 for iPod touch/iPhone and Onkyo Remote for Android provide an
alternative way to operate Onkyo network A/V receivers. A simple yet powerful
Graphical User Interface allows the user to control input sources, adjust audio
settings, and control playback across multiple zones in the home, from anywhere

Fantastic receiver

Best bang for the buck I've ever had in a receiver before. 7.2 channels expandable to 9.2 with external amplifier. The sound is fantastic. Also love the Audyssey MultEQ XT32. It may be 2 years old, but it still holds up well against todays receivers minus HDMI 2.0 and features such as Dolby Atmos. For the price, nothing else comes close.

Excellent Quality, not for beginners.

The sound of this receiver is clearly several steps above my current Sony 1010, I really puts out a pure signal to my DefTech 8080 system. What it doesn't excel at is simplicity. If your willing to put the time in to tweak the system literally over weeks, its a great system. You can use the the Audyssey MultEQ® XT32 and get 90% but the last 10 does take a while.

Onkyo TX-NR818

Surround set-up is a snap and sound is great. Not so easy to set-up and use multi-channel zones. Remote is near useless for second room use -- blew out ceiling speakers as the sound level was inadvertantly set too high, even though system cap of 70% was set. Was trying to get set quickly for holiday parties and did not take the time to read the 150+ page manual to learn intricacies. Once the remote apps were loaded, it was much easier to control volume and net radio selections in sevond zone. The net link for both wired and wifi went out...could not find an eay fixin the manual. Tech support suggested unplugging the system for 5 seconds and that did the trick. Nice selection of net radio whrn the links are working.

Lots of options with this system, though it is now discontinued. Hear the relacement models offer less, so happy i got it when i did. Tech help at Crutchfield is phenominal, worth any small premium you may have to pay. Onkyo help was okay, but not as friendly.

I am a huge fan of Crutchfield and will look there first for any future needs.

Onkyo 818

This is my first THX and Onkyo brand receiver and it is AWESOME. I have 4 Bose satelite, 1 JBL center and JBL 12" powered subwoofer speakers. Sound is so awesome cool that we now enjoy more in watching movies and listening to music. As always, Crutchfield's amazing customer service made all my purchases so smooth. I have been a Crutchfield happy customer for 15 years.

Onkyo TX-NR818

I have had this unit for a few weeks now. Still working on the settings, but nearly set up. Plenty of power and the set up options are extensive. Unit is robust and pushes clean power to my 7.1 set up. You can't beat the price break of the outgoing model!

Pros:Set up options are extensive.
Remote may replace my harmony one as an universal remote.

Cons:Display screen for a unit this size is underwhelming and below average.

my 3 week review ONKYO TX NR 818

I will rate this with 5 stars, even though there is some things I don't like about it. the few things I don't like are as follows(1) no 12 volt trigger for main use, only for zone 2 and 3. (2) no back lit remote. I have had it 3 weeks and now the things I like (1) the video processor, didn't expect it , but it has mad a big difference in color and quality of my movies( the colors is just amazing) ..(2) AUDYSSEY XT 32....WOW is all I can say, after my 1st run of it..didn't think I was really impressed, after listening to some stuff in a few movies, my system came alive...bass soooo deep all around tonal balance, now movies sound so much better, im pretty impressed now that I have had some seat time, so happy I bought this( replaces a Yamaha HTR 5890) ..this has been well worth the money spent...and BTW no HDMI issues ..has 2 built in maybe 4" fans and has not even came close to getting hot enough for them to come on( not in a enclosed cabinet) do have gear on top, but have a 2" space between for good air flow....I will try to do another review after a few months, hopes this helps you decide

Pros:features for the money, audyssey xt 32,video processor

Cons:no 12 volt trigger for main, only triggers for zone 2 and 3... No back lit remote

Onkyo TX-NR818

Owned for about 2 weeks now. So far so good. Nice surround (I'm set up for 7.1). Setup is easy if you take the time to follow along in the owners' manual. The easiest way to do that is by having a laptop with you, because the manual is on a disc only, no booklet.

Pros:Power, Features, Looks, Ease of hook-up and set-up.

Cons:none yet, but I hope this newer construction model is better than my previous model, because the HDMI board went out after less than 3 years. Fingers crossed!

My Onkyo experience

I've purchased 3 Onkyos' in the past, every purchase has proven better every time. My last purchase is an Onkyo TX-NR818, excellent a/v. I love the clarity and separation of the sounds, I also like the way Onkyo calibrates the unit with the special microphone, I'm very happy with my receiver, although I must say I had to return my Onkyo TX-NR818 because the first one had a problem when I was playing music the unit was making a popping sound between tracks, or when watching tv the popping sound was between commercials or back the regular programming, I believe it was damaged by UPS in the way they handle packages, the carton was broken and the inside foam ends were also broken. But Crutchfield has a 60 days return policy and they exchanged it for me. Great experience.

Excellent receiver

Agree with previous reviewers on what a great system it is. I have a BluRay, HDTV, CD player, FIOS box, tuner and hard-wired internet. We use the Net input a lot and it streams Pandora & Spotify easily. I have a 5.1 setup in the family room (small room 11x12 and odd shaped) and a 2 speaker setup in Zone 2 which works superbly. Easy setup (plug everything in, turn it on, run Audyssy, enjoy ). Had it about a month and zero issues so far.

Cons:- Remote is not backlit. Can be annoying especially if you watch movies in a dim room. I upgraded to a Harmony Touch universal remote that I LOVE (and solves this problem entirely & replaced all my other remotes) !!!
- It is BIG & sticks out of my entertainment center even more with all the connections in the back.

good sound receiver

Oh, yes! The sound is worth the effort of setting this monster up. I'm old -- digital electronic equipment baffles me. I used to keep up with changes in audio equipment during the 60s through the 80s, the BAM! It started happening too quickly and I started slowing down too rapidly. Throw in all the video stuff and I became an anachronism. HOWEVER...I persevered and got my digital cable, stereo music, turntable, DVR, VHS tape, set top box, etc., etc. all up and cookin'. It took me a couple of days on and off without any available Crutchfield help (aggravation cool-down periods included), but it's done (except the Wi-Fi thingie) and I can now heartily recommend this receiver. I probably should've called Crutchfield for help, huh?

Pros:The sound produced bt this receiver is the best I've ever heard in my own home. TV, radio, audiophile vinyl, you name it...it is awesome.

Cons:Hooking things up was very aggravating for me, especially because there was no owners manual included other than a quick start guide. I wish these doggone companies would return to respecting their customers enough where they will print and include manual with a purchase. Sheesh already!

Great receiver

Written By Mike, Tucson, AZ on Wednesday, December 11, 2013

It's a great midline receiver. I'm running it as a 9.2 with and external amp. And works great for the mid sized room it's in. The kids love the sound when playing games and turns a movie into a theater.

Awesome!

My 7.1 surround system just woke up! Cannot begin to compare how the 818 has awoken my speakers and complete system with much more detail and balanced sound than from my old Onkyo TX-SR804. While my 804 was no slouch and is still going strong (going to the bedroom to upgrade my current surround system there), this new 818 sounds amazing in comparison. Set up was time consuming but well worth the improved sound accuracy. Did not know what I was missing! We'll see how it stands up over the long haul. If my 804 is any indication this 818 should keep providing amazing surround and stereo sound for many years to come.

Onkyo TX-NR818

I purchased the Onkyo TX NR818 due to its mass amounts of features it has at this sale price. I dare you to find another receiver at this price with something even close to these specs.

Setting and configuring up is a breeze using the onscreen guide. I love the dual HDMI output, one goes out to my projector while the other output is to a monitor.The Audyssey 32XT is great for self-calibration (i then fine tune with SPL meter). Although the receiver has Dual Subwoofer outputs, the version of Audyssey on this receiver does not have multi subwoofer calibration.

My setup consists of a 7 channel external amp powering my Klipsch Reference speakers and dual PSA subwoofers. This Onkyo receiver is capable of outputting 9.2 surround sound (Either Wide OR Heights but not both) with an external amplifier. I had an old pair of Polk tower speakers so that I can test out 9.2 (Front Wide mode). The Onkyo is powering my front main speakers. If your room is wide enough having front wide speakers really opens the front sound stage!

The remote buttons are laid out nicely. I love the onscreen volume and audio information since my receiver is in a closet. The remote app on my Android phone, is a neat option. I have my Onkyo hardwired to my network so everything is instant. When connecting an iPod via USB, I am able to use my phone like an iPod to view and play songs (same for online radio).

Overall I am one happy camper and do not see myself upgrading in the future.

TX-NR818 Works Great - Does what I want

Overall, I really like the receiver. I upgraded my old unit (ONKYO TX-SR805) 1) Because I wanted the ability to run an output to my TV or to a projector when we watched movies. 2) I wanted the HDMI pass through when the unit is off, and 3) I wanted to use my home network to play music from my phone or my computer through the stereo. On all three counts, the receiver worked very well. The sound quality is very good. There is plenty of power and I can Bi-Amp my front speakers (Polk RTi-A9). Getting an app for my Android (Motorola Atrix) to control the receiver and select music on my computer is great too. I haven't had any trouble with the unit. (except that the first one that I received was defective and had no sound output whatsoever - it almost seemed like it wasn't fully assembled in the factory - Malaysia) The only thing that is a little funny is that when switching from one source to another, or when turning the unit off to use the pass through HDMI, there is a delay of a second or three. I guess that is normal (???), but I have an uneasy feeling when the delay is there. It always switches over after a few seconds. (I had a Marantz unit that didn't fully switch frequently so I returned it and bought this Onkyo unit.) I've been very happy with the TX-NR818.

Pros:HDMI Passthrough, Two HDMI Outputs, Networking music from my computer.

Gaylord

Had adenon av receiver for a week . It overheated twice. I sent it back and obtained the onkyo 818. The onkyo wighs 50 pounds. It has a giant transformer. Electronics are not as good as transformers to make the wattage.This is why old fluorescent fixtures lasted longer than the new ones . The onkkyo 828 weighs 40 + pounds.They are moving toward electronics . You figure it out.

GREAT RECEIVER!!!!!!!

I love Onkyo products!! The salesman recomended this to me as the best bang for the buck!!! It really makes my Klipsch reference speakers come to life!! Very clean power!! This doesn't get hot like my Sr 706 did!! The built in cooling fans are awesome!! I LOVE THE NETWORK CONNECTION SO I CAN LISTEN AND WATCH ANYTHING OFF MY NETWORK HARD DRIVE!!! RECOMEND THIS 1000% ITS A MUST HAVE IF YOU NEED POWER!!!

Nice upgrade from my 806

I like this receiver a lot. Big improvement on my 6 year old Onkyo 806, which I also liked. Seamlessly handles wifi, streams Pandora in a very transparent way, very good at music and very good at 5.1 with the potential to add more speakers. I am very happy that I bought it.

Pros:Easy to set up, very good sound, good wifi links with the extra adapter.

The Onkyo 818 is a Winner!

I am thoruoghly impressed with the 818. It has a wow factor. I bought it to replace my 808. The picture quality is superb and the sound is amazing. Although I only have a 5.1 set up, this unit was worth the investment. I have a wireless sub that works without a hiccup. The Bluetooth capability is a nice addition as well as the availability of the 8 HDMI inputs. The only drawback is that the remote is not backlit. I think that this price represents a fair price point for this receiver. I was somewhat skeptical about buying another Onkyo receiver at first, because the sound went out on the 808 and the Onkyo people were not too helpful, but the service and help I received from Crutchfield is worthy of note. They were always easy to contact and willing to help with all of my questions from brand comparisons to set up.

Pros:Picture and sound quality, easy set up, the fact that the unit runs cool and its price make this an attractive receiver.

Cons:The remote is not backlit which is somewhat hard to understand given the price and quality.

Onkyo does it again and Crutchfield delivers the price!

My 2+ yr old TX-NR808 quit playing sound (can you believe it?) Onkyo agreed to fix it out-of-warranty, but I had heard repairs take months(it was only 3 weeks) and so I ordered this one to replace it, thinking I could use the old one at our lakehouse or sell it on Amazon, meanwhile upgrading to the TX-NR818. There were a few upgrades I was interested in; Bluetooth playback from iphone, the new Audessey speaker setup, 2 more inputs. Crutchfield had the best price with free shipping and the Bluetooth addon included free, so I ordered from them. They got it two me in a couple or three days (great service, as we expect now) and I got it hooked up in short order as I had marked all my previous inputs and outputs. I ran the Audessey speaker setup once I got the baby to be quite for long enough and was done. My son said it "is the best surround sound I've ever heard". This was playing thru a Bose Acoustimass 5.1 system. Almost identical to the TX-NR808, which I loved and with the upgrades, it's super. This review is off the cuff, from memory, I didn't go back and verify all the terms and feature names I used.

Great Reciever

Awesome receiver. This thing has plenty of power to fill a 30 foot by 20 foot room with amazing sound. I currently have it hooked up in a 7.2 configuration but plan to shortly add another amp to drive channels 8 & 9, can't wait to hear 9.2 sound. Tons of features and adjustments which to me is a good thing to be able to adjust precisely how I want it.

Pros:Tons of features which for me is a good thing. At the same time if you want simplicity you can go through the basic setup and you'll be fine right out of the box.

Friends, you will forgive me. But to understand how much this receiver is inferior to the other in sound quality and equal in value, they must listen together. I did not, therefore suffered minor costs. I wish you to avoid my errors.

Onkyo TX-NR818

I have owned this receiver for a couple of weeks and am thoroughly impressed. It supplies loads of crystal clear sound to my 5.1 speaker system and is intuitive to use. I bought it to replace an old Onkyo receiver that wasn't exactly what I had hoped it would be, but early signs are this might be all I will ever need. It is the receiver I've always wished I could get.

Pros:Loads of power and crystal clear sound, very clear display, online features are great, this is an awesome workhorse.

TX-NR818

I bought the 818 to replace my 806 which was having the HDMI board capacitor problem. One of these days when I get time, I will try to relace the capacitors and if this fixes my 806 problems, I'll give the 806 to my son. The 818 was a piece of cake to install as the replacement. I am very pleased with the 818's performance and ease of installing. The price from Crutchfield for the TX-NR818 was also very attractive.

A good A/V receiver.

I am still trying to figure out how to use. I replaced a previous Onkyo unit, I was looking for more updated unit.. I miss the switched outlet for my powered subwoofer and speakers, I have to do that manually through a power strip. The Manual is on a CD which is slowing my learning process. Unit performs well as with all new electronics there is a learning curve. I know if I have a problem Crutchfield will help. I recommend the unit for a home audio/video system. I probably would give the unit 5 stars, but haven't finished using all the features.

Pros:Remote is easier to hold than my previous Onkyo remote.
Onscreen setup is really convenient and easy to use.
I have no had a chance to install the wireless adapter.

Onkyo TX NR818

I am impressed with this receiver. With 135 watts output per channel, this unit rocks the man cave. Simple hook-up replacing the Sanyo unit that had expired-and the difference was amazing. Once I ran the initial set up with the Audyssey speaker optimizing system, I began to experience surround sound like never before! My Polk Audio speakers have never sounded so good. My powered sub is pumping out base that I have never heard from it before, really enhanced the audio available from some of my blu-ray discs. Exceptionally pleased, and as usual, the service and prompt shipment from Crutchfield remains unmatched.

Onkyo TX-NR818

Superior receiver. Programmable inputs are nice. I have it connected to Polk Monitor Series 50, TSi200 and CS20. Great sound that will knock you out of the room if you like. Down low it is crisp and clear. Runs a little warm but that's what 135w/channel will do. It's the upgrade I've always wanted.

Onkyo 818

I've had this unit for a few weeks now and haven't found any faults that are worth mentioning, with the possible exception of input choices as I have several component video units that seem to be over-ridden by the HDMI inputs that are assigned to the same input. It is entirely possible that both inputs can be used by switching between them and I just haven't taken the time to figure out how to switch them yet.

I'm coming from two aged receivers (Denon AVR2500 and Yamaha 5590) and for power output, clarity, separation, and control this Onkyo unit does not disappoint. I found the GUI to be intuitive, the remote easy to use, and the USB and Net features function well. Phono input is a bonus for my Denon player. The Audessy 32 sounds truly remarkable IMO, and really is a nice improvement to my setup. I will mention it took several attempts at updating firmware BUT, I'm using the Onkyo wifi USB plugin for net service (which I don't recommend, BTW) and after a couple of failed updates it finally updated. I did have to run Audessy again and adjust my input levels again but it wasn't a big deal. Overall, so far I am very happy with this unit and after struggling for weeks over the Denon 3313, NAD 757, Marantz 6007 or this unit all at the same price, I believe for my intended use of music and home theater with tons of flexibility, I made the right choice.

Pros:Tons of power, nice construction, incredible array of options, good GUI, decent remote, good looks, Audessy 32. I'm a believer that high power and low frequency = high weight, and at 40 lbs this unit fits the bill too. Have a nice cabinet or very sturdy shelf......

Cons:Updating firmware may take a few attempts, but not a big deal really. Net services seem flakey BUT this could be caused by the wifi USB adaptor I'm using, which I don't recommend. Haven't tried a hard wired connection yet.

The Journey

I originally purchased a Denon from Diymicro but it came in a seriously beat up, previously opened box. They were pawning a demo off as a new unit on me so I sent it back. I noted that Denon had gotten seriously lighter over the years and wondered about the sound quality. Low frequencies and high power equal big heavy components. I went back to researching and decided on the Onkyo. This is a heavy unit with two cooling fans internally which is very good since a common complaint over the years with Onkyo is heat. Hooking it up was relatively easy. I found the Audyssey MultEQ XT32 set up using eight test locations to be a really good way to go. I don't know how it manages to do it but it fills the entire room with a very nice balance of sound. The power is good and the processing automatic and seamless. I don't find the app for the itouch to be as intuitive as advertised but works well now that I am familiar with it and it is very handy for zone two. I am very happy I took the extra time and went with this unit. Crutchfield is a good reliable business partner. I can't say the same for Diymicro.

Pros:Excellent sound and processing. It works automatically and there is little need to monkey with it. Connectivity with the internet is a giant leap forward. Internal cooling fans cure the heat build up issues in my cabinet and will extend the life span of the components I am sure. The remote control actually works without forcing an additional expense to go with a Harmony or similiar. Nothing more frustrating than dumping this kind of money and finding a cheasy remote to go with it.

Cons:The remote control app for the itouch was not "intuitive" as advertised. Maybe I am not their ideal test subject but I found it tricky to learn. Once I got it figured out though it is a great way to go for zone two.

My Third Onkyo AV Receiver

It is hard to add anything to all the wonderful reviews on the Onkyo TX-NR818. For me in my home theater it did everything and more that I wanted. This is my 3rd Onkyo AV Receiver that I bought from Crutchfield. It's funny, but it works out that I bought one every 5 years of the same basic model but upgraded. For me, I have a Panasonic 3D projector. My older Onkyo would only pass 3D on one channel. This unit has 8 HDMI inputs and 2 HDMI outputs. Wow. No problem with all my inputs. I use them all with remote switching. This HDMI switching device is everything I dreamed of. My last one only had 3 HDMI inputs. It upgrades the picture noticeably to 1080. It is capable ot upgrading almost 4X that to 4K. Sony now makes a projector that is capable of 4G and I have read a review of a AVS member that has that setup and it is outstanding according to him. But the Audyssey Dynamic EQ 32 really puts it over the top. It comes with a mic and you need a camera tripod to automatically tune your speakers. I could not believe it but it told me my center speaker which was no slouch was unacceptable and it could not go on. I switched that speaker in the system and where ever is put is Audyssey turned it down. I researched and bought a Polk CS20 from Crutchfield and Wow. It is like magic. My whole audio theater experience changed pleasingly for the better. I have no idea how they did it and I have two subs that came into their own. Check out reviews at AVS and Amazon.
